Depends how bad the rotors were. And how old the pads are. The pads will wear into the shape of the rotor surface. So new flat rotors will wear old pads much faster until they wear down to conform to the new surface. Also this could damage the rotor surface. Its cheap insurance just to put new pads in. Its a quick job since the brakes are all apart anyway.
When rotors need to be changed usually the pads have worn down. It is always a good idea to change pads when changing rotors.
Replace the pads, and the rotors. You need to change the brake pads and the rotors.
You do not need a torque wrench when replacing brake pads and rotors. Some of the tools needed to change the rotors and pads are the c-clamp, sockets, wrench, grease, and brake cleaner.
As long as your rotors are not warped, or you have not let the brake pads wear to the point they defaced the rotors, there is no need to change them. Just install new brake pads. Rotors can last the life of the car.
no
Its a good idea to change the pads because the old ones may have worn unevenly. That may cause future damage to the braking system. If you just need to get by then its ok to used the old pads but most of the time the rotors cost more then the brake pads. I WOULD CHANGE THE PADS.
I don't know if you are saying you have the new hubs and rotors and still have pulsation, or if you are asking what causes pulsation. If you have pulsation on slowing this is due to warped rotors, and you need to change the rotors and the brake pads, not the hubs. Not too expensive: 2 rotors and brake pads for my Pontiac is about 55 bucks. DIY of course.
It will cost approximately $30 per wheel to change the brake pads, at a auto mechanic shop. It will cost more if the rotors need to be replaced. You can purchase brake pads for approximately $10.
You will need to remove the tire and wheel from your 2005 Dodge Durango. Remove the brake pad Springs and calipers. Tap the rotors with a hammer to loosen them. Slide the rotors off. Reverse the process to install the new rotors and brake pads.
remove tire calipers brake assembly then pull your rotors off i would recomend putting new brake pads if your putting new rotors you will need a special puller for the rotors cause they are pressed on
The brake rotors only need to be changed if they are worn beyond allowable specifications and should be changed in pairs. They do not need to be changed with the pads unless they are damaged as above or warped.
depends on the condition od the pads. If worn or have groves etc from the rotors then replace.
